Splunk Search

How do I create searchable fields from a single raw string?

Hi,

I have syslogs that I would like to search for by ZONE (UNTRUST) and IP (12.12.12.1). Below is a sample of how the data is formatted as one long field. I would like to be able to do a search on ‘UNTRUST’ and then sort/count by IP (10.10.10.10) and Port (80).

Syslog sample: UNTRUST/12.12.12.1(80)

Any help would be greatly appreciated.

TIA

You probably want to create and save field extractions. There are several ways to do this: Overview of search-time field extractions is a good place to start.

However, if you don't want to do this, you can create and use temporary fields with the rex command like this:

sourcetype=syslog untrust*
| rex "UNTRUST/(?<IP>.*?)\((?<Port>\d+)\)"
| stats count by IP Port
